金属预成冠与纳米树脂修复乳牙龋源性露髓的疗效对比研究

Comparative study on the stainless steel crown and nano-resin in repairing carious pulp exposure of deciduous teeth

摘要:

目的 探讨金属预成冠（SSC）与纳米树脂修复乳牙龋源性露髓对患儿咬合功能恢复和咀嚼疼痛的影响。方法 回顾性分析梅州市人民医院2022年2月—2024年5月收治的91例龋源性露髓患儿（共168颗患牙）的临床资料，按照不同的治疗方法分为对照组与观察组。患儿均行根管治疗，对照组（46例，86颗患牙）根管治疗后采取纳米树脂充填修复联合氢氧化钙糊剂根管填充修复，观察组（45例，82颗患牙）根管治疗后采取SSC修复联合氢氧化钙糊剂根管填充修复，比较两组治疗效果。结果 观察组治疗总有效率高于对照组（P <0.05）。观察组咀嚼功能优良率高于对照组（P <0.05）。观察组疼痛程度低于对照组（P <0.05）。观察组治疗后最大咬合接触面积和最大咬合力均大于对照组（P <0.05），菌斑指数（PLI）、牙龈指数（GI）、龈沟出血指数（SBI）均低于对照组（P <0.05）。治疗后两组最大咬合接触面积和最大咬合力均升高（P <0.05），PLI、GI和SBI均降低（P <0.05）。观察组治疗前后最大咬合接触面积、最大咬合力、PLI、GI和SBI的差值均大于对照组（P <0.05）。观察组并发症发生率低于对照组（P <0.05）。结论 采取SSC修复联合氢氧化钙糊剂根管填充修复治疗龋源性露髓患儿，可提升牙周健康、咬合功能和咀嚼效率。

Abstract:

Objective To analyse the effect of stainless steel crown (SSC) and nano-resin on the recovery of occlusal function and chewing pain in children with carious pulp exposure.Methods Ninety-one cases of children with carious pulp exposure with a total of 168 teeth admitted to Meizhou City People's Hospital from Feb 2022 to May 2024 were retrospectively selected and divided into two groups according to different treatment methods, both groups were given root canal treatment, the control group (n = 46, 86 teeth) was treated with nano-resin filling restoration combined with calcium hydroxide paste root canal filling restoration, and the observation group (n = 45, 82 teeth) was treated with SSC restoration combined with calcium hydroxide paste root canal filling restoration, and the observation group was treated with SSC restoration combined with calcium hydroxide paste root canal filling restoration. after root canal treatment, the observation group after root canal treatment with SSC restoration combined with calcium hydroxide paste root canal filling restoration, to compare the effect of the two groups.Results The total effective rate of treatment in the observation group was higher than that in the control group (P < 0.05). The excellent rate of masticatory function in the observation group was higher than that in the control group (P < 0.05). The pain degree of the observation group was lower than that of the control group (P < 0.05). After treatment, the maximum occlusal contact area and maximum occlusal force in the observation group were higher than those in the control group (P < 0.05), while plaque index (PLI), gingival index (GI), sulcular bleeding index (SBI) were lower than those in the control group(P < 0.05). The differences of maximum occlusal contact area, maximum occlusal force, PLI, GI and SBI in the observation group before and after treatment were greater than those in the control group (P < 0.05). The complication rate of observation group was lower than that of control group (P < 0.05).Conclusion Adoption of SSC restorations combined with calcium hydroxide paste root canal filling in children with carious pulp exposure improves periodontal health and occlusal function and masticatory efficiency.
